WILLIAM HENRY HOYLE AND THOMAS BARKER, OF BOLTON, ENGLAND.

ELONGATING-MACHINE.

To all 'whom it may concern:

Be it known that we, TVILLIAM I-IENRY IIorLn, cotton spinner, and THOMAS BAKKER, consulting engineer, subjects of the King of Great Britain and Ireland, residing, respectively, at- 86 Chorley New road, Bolton, in the county of Lancaster, England, and 352 Church road, Smithills, Bolton aforesaid, have invented new and useful Improvements in or Relating to Elongating-l/achines, of which the following is a specification.

This present invention refers to improvements in or relating to elongating or drafting or it might be combined elongat-ing or drafting and spinning machines of a new class invented by us for the production of re-condensed yarn, and which machines or parts thereof are patented in the United States of America under Numbers 708,046 and 739,877. In such apparatus, the elongating is performed by wire covered cylinders, and a group has comprised a main cylinder, a fancy and a doffer, and is clearly set forth for the first time in our Patent io. 708,046. One great problem in connection with our new apparatus has been to obtain, a full, round, even, and uniform yarn, and we are constantly experimenting to this end. TWhile thev desired object has been very largely attained by us, we are seeking,y by this present invention, to more satisfactorily prevent one section from robbing another, and the production of uneven ends. As the result of experiments, we attribute this robbing or production of uneven ends, and the dispersal of liber, to the action ofthe fancy 7, which runs at a surface speed in excess of the main cylinder. IVhile its function is to lift the fiber ready for the doifer we have found in practice that it has exceeded this duty and has to some extent dispersed a portion of the fiber so that the same is deposited in detrimental situations on the doffer with the inevitable result that robbing of ends has occurred and uneven yarn has been produced. According to our invention we use means which prevent this dispersal of fiber and protect the doffer against dispersed fiber. Various devices may be used for this purpose but the one we at present find the best, is, what we may term an intermediate or intercepting roller or cylinder which is wire-covered and is caused to rotate intermediate of the fancy and doffer.

The attached drawing illustrates the in- Speccation of Letters Patent.

vention, and shows so much of the part-s of the new elongating machine as is necessary to fully set forth the advance.

In the said drawing z-Figure l is an end elevation and indicates part of the main cylinder, the fancy, and the doffer of the elongating machine, together with the driving gear. The fancy and doer are disposed or arranged in such manner as allows the introduction of the new intermediate or intercepting cylinder or roller, which is shown in working position. Fig. 2 is a vertical sectional view of the wire clothed parts seen in Fig. l. Fig. 3 is a detail view.

In carrying out our invention we arrange the fancy b and doffer c with such relation to the cylinder a as to leave space for the introduction of an additional wire covered cylinder or roller d. This wire covered cylinder or roller cl is what we term the intermediate or intercepting roller and is mounted and driven in any convenient manner so as to revolve in the same direction as the fancy. In the way shown in the drawing, the new intermediate or intercepting roller d is carried in bearings formed in brackets e having a removable cap, and each such bracket c is bolted to a bracket f secured to the bend g, the bracket e being adjustable radially with respect to such bend and the bracket f adjustable angularly around the bend. A bolt and nuts /z passing through curved slots, bolts the two brackets to the bend, and adjusting studs or screws z' z' bearing against a lug or ear z" on the bend, serve to give nice adjustment around the bend, while the stud bolt or screw y' serves the same object in setting-up the bracket e radially that is in direct line with the main cylinder center. The intermediate wire covered cylinder or roller CZ closes up the gap between the fancy Z2 and doifer c and receives on its teeth or dents any fiber thrown olf, thus, not only preventing dispersal, but effectually guarding the doffer. Any released fiber having such a short distance to travel, has not time to spread before it reaches the dents on the wire covered roller d. The fiber collected on the intermediate or intercepting roller is stripped therefrom by the main cylinder a as it revolves, the doifer constantly collecting from the main cylinder in the usual manner.

By way of indication, and to disclose our advance to the fullest extent, We here state that at present we are running the main cylinder c between 300 and OO revolutions per minute, the fancy at about 25 .per cent. quicker surface speed than the cylinder, the new intermediate cylinder or roller at about 40 revolutions per minute, and the doffer at about 40 revolutions per minute. It is to be understood that these speeds are merely given as an example and we. wish to reserve the greatest latitude in this respect. IVe may as the result of further use and experr ence decide to run at what may prove more beneficial speeds and we may require to vary the speed or speeds of some or any of the Wire covered cylinders or rollers when dealing with different classes of material.

l The revolving wire-clothed parts capable of being inclosed are housed in ordinary fashion, and 7u indicates a sheet metal casing conveniently hinged at 7c.

In the system of gear driving shown, the spur Wheel l on the doffer shaft drives a carrier wheel 2 gearing with a spur wheel 3 on the shaft of the intermediate or intercepting roller (Z.

The fancy is driven from a spur wheel 4 on the main cylinder a, gearing into spur Wheel 5 these gear wheels being on the opposite side of the machine to those lettered l, 2 and 3 and suoli fancy is supported in a way similar to that described with reference to the new intermediate or intercepting roller (l. The way of supporting and driving CZ may obviously vary. `We might arrange to drive the intermediate or intercept ing roller Z in the reverse direction but in that case its speed would require to be varied and we do not contemplate following such a course.

The essence underlying our invention for intercepting and collecting liberated fiber in machines of the indicated class, having been fully set forth, we reserve the right to modify the means to carry out our invention.

`We declare that what We claim is l. In an elongating machine, a wire cloth cylinder to which the material is fed in sections, a card wire clothed fancy, a wire clothed dotfcr, and a card wire covered rotating' shield positioned to extend between the dotfer and the fancy, and adjustably mounted.

2. In an elongatinO' machine, a wire cloth cylinder to which the material is fed in sections, a fancy, a doffer, and a driven wire covered roller filling the gap between theV dotfer and fancy and acting as a shield to insure the fiber sections being preserved.

3. In an elongating machine, a wire cloth cylinder to which the material is fed in sections, a wire covered doffer, a fancy, a wire clothed rotating shield filling the gap between the fancy and the doffer and rotating in the opposite direction to the main cylinder, adjustable supporting` means for said shield, and means for rotating the wireclothed rotating shield, as set forth.

d. In an elongating machine, a wire cloth cylinder to which the material is fed in sections, a wire covered doffer, a fancy, a wire clothed rotating shield for the doffer, adjustable supporting means for said shield, and spur gear for rotating` the fancy, the dolfer, and the wire clothed rotating shield, as set forth.

In an elongating machine, a wire cloth cylinder to which the material is fed in secA tions, a doifer, a fancy, a wire clothed rotating shield rotating oppositely to the wire clothed cylinder, gear for driving same, a fixed lug z, a bracket f, screws t', z', in said bracket bearing against a fixed lug for adjusting the position of the bracket, a bracket c, means for adj ustably mounting such bracket on the bracket j, and inclosing means, as set forth.

G. In an elongating machine, a wire cloth cylinder to which the material is fed in sections, a dolfer, a fancy, a wire clothed rotating' shield roller, spur gear for driving said parts, a fixed lug vl, a bracket f adjustable by screws c', bearing against said fixed lug i, a bracket c adjustably mounted on said bracket f, means for setting-up said brackets, a grooved bracket fixed to the pedestal cap for the fancy and intercepting roller brackets, and a hinged cover 75 as dea scribed.

7. In an elongating machine, a wire cloth cylinder to which the material is fed in sections, a rotatable card wire cloth cylinder, a rotatable card wire cloth fancy, a rotatable wire cloth doifer, a rotatable wire covered shield located between the doffer and the fancy, and means for rotating said rotatable members said means being so proportioned and arranged that the surface speed of vthe fancy is greater than the surface speed of the cylinder and the surface speed of vthe shield is less than the surface speed of the cylinder and the fancy.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
